Cracking a Bull Whip in Real Slow Motion

Kudos to Adam Winrich for making me want to learn. ( : (check out his amazing whip videos and tutorials on Youtube) To crack a whip, you must send a loop down the whip. This loop travels down the whip moving from more material down to less material. This transition of material is what makes the whip work. For a theoretical example, if you input 100J of energy at the handle of the whip, where there might be 100g of material, that energy doesn't dissipate when it reaches the end of the whip where there might be 25g of material. That energy may now be something like 400J of energy due to the less material it has to occupy. Those figures are completely theoretical, but can help you understand why a whip works. A whip makes the iconic "crack" sound due to the tip breaking the sound barrier (roughly 700mph, I think). A sound pressure traveling faster than the sound barrier will create a sonic boom. This sonic boom is what you hear as the "crack." In an attempt to see what a whip is doing at these speeds, I recorded myself cracking a 10 foot braided leather bull whip at 300 and 600 frames per second. Here are the results. BGM - "Following Your Footsteps" by me (Yes, I know the music doesn't match the video what so ever...but it was perfect for the length of the video. Lol)
